Gameplay doesn't exist. I don't know what that is as I don't own Nintendo Gameboy and I know this game is different from crap on that rubbishware, so I guess it's not featured here.
The story feels like reliving some medieval area, but it's not just classic "drama", it has twists and it's not boring at any moment.
There are a few fetch quests (go huntin' or at butchers, bring meat/skins) but the rest of sidequests aren't meaningless and are fun. Some are disturbing, it ain't a show for kids. Every single quest, main or side, you can solve in different ways. Not just two. More.
No grind needed anywhere. This also applies to fetch quests I mentioned above. Those are moneyearners for players who won't use other means like thieving, feel free to skip them all. You don't have to pick a single flower in the whole game, you can train strength elsewhere and you can buy or loot alchemy ingredients instead of collecting them from mother nature.
In case you're wondering, I'll most probably vote for it as goty. Not 100% certain as the year will get more interesrting entries. Hint: Yakuza 0 next month.
